Abstract
A web material processing machine (10) for producing a multi-layered material (12), especially a multi-layered packaging material (13), is presented. It comprises a first vacuum coating unit (28) for deposing a film of a first coating material on a web material (16) to be processed. Moreover, it is equipped with an extrusion coating unit (32) for extruding a film of an extrusion material on the web material (16). The extrusion coating unit (32) is positioned behind the first vacuum coating unit (28) with respect to a processing direction (20). Additionally, a method for producing a multi-layered web material (12) is explained. Furthermore, a multi-layered packaging material (13) is described.
Claims8
An in-line web material processing machine for producing a multi-layered material, especially a multi-layered packaging material, in particular a monomaterial, the in-line web material processing machine comprising:
- a first vacuum coating unit for deposing a film of a first coating material on a web material to be processed, and
- an extrusion coating unit for extruding a film of an extrusion material on the web material to be processed,
- wherein the web material and the extrusion material are made essentially of the same material,
- wherein the extrusion coating unit is positioned behind the first vacuum coating unit with respect to a processing direction;
